Why the study?
Does twin gestation cause more profound changes in maternal cardiac function compared to singleton gestation?
Does twin gestation cause more profound changes in maternal cardiac function compared to singleton gestation?
Normal twin pregnancies induce more profound maternal cardiovascular adaptations, specifically higher cardiac output and lower total vascular resistance, compared to singleton pregnancies.
Answers are grounded in this paper and cite their sources.
May inform twin-specific cardiac monitoring thresholds; leaves open links to maternal outcomes.
In twin gestation, maternal cardiac function apparently undergoes more profound changes compared with in singleton gestation, as testified by higher CO and lower TVR values at each stage of pregnancy starting from the mid-trimester.
